ABSTRACT 

The purpose of this Bureau of Mines report is to provide mining indus- 
try personnel and regulatory authorities with a subsidence-reference 
list and annotated bibliography that will aid them in locating sub- 
sidence information and in developing their own subsidence information 
sources. Over 700 references are listed in the Bureau's subsidence in- 
formation center bibliography; approximately 600 of these references 
were obtained for assessment. Of these 600 references, 167 were select- 
ed to be rated, categorized, and annotated. All literature referenced 
in this report was published prior to 1984. Table 1 is a cross- 
referenced index that classifies and rates selected references with 
respect to specific keywords. References are rated not on quality of 
content but rather on applicability to given subject areas. Appendix A 
is an annotated bibliography of the references listed in table 1 and 
provides further information on each article to aid the user in select- 
ing articles for specific areas of subsidence technology. Appendix B is 
a copy of the subsidence information center bibliography.

INTRODUCTION 



This Bureau of Mines report identifies 
sources of subsidence information that 
are often unknown or unavailable to mine 
industry personnel. Its purpose is to 
assist the mining industry and regulatory 
authorities by providing a subsidence- 
reference list and annotated bibliography 
that will aid them in locating subsidence 
information and in developing their own 
subsidence information sources. 

A subsidence information center was 
started at the Bureau's Denver (CO) Re- 
search Center in 1980 to create a sin- 
gle, central, and comprehensive source 
of available state-of-the-art subsidence 
literature and provide this information 
to mine operators attempting to limit or 
control mining-related subsidence damage. 
An intensive literature search was per- 
formed to compile a comprehensive subsid- 
ence bibliography. This search included 
the use of computerized information re- 
trieval systems, published bibliogra- 
phies, and individual assessments of sub- 
sidence article bibliographies. At the 
end of 1983, the bibliography contained 
over 700 references with approximately 
600 subsidence references available for 
consultation at the Bureau's Denver Re- 
search Center. From these available 
references, articles were selected and 
annotated; the procedures used for se- 
lecting articles are described later in 
this report. All annotated articles in 
this report are on file at the research 
center. 

The Surface Mining and Reclamation Act 
of 1977, Section 516 (b)(1) of Public Law 
95-87, requires mine operators to adopt 
"...measures consistent with known tech- 
nology in order to prevent subsidence 
causing material damage...." 

This report outlines available litera- 
ture that pertains to state-of-the-art 
subsidence technology, developed in the 
United States and abroad, that will as- 
sist persons developing subsidence con- 
trol plans. Included in the literature 
is information on subsidence-predic- 
tion methods, subsidence-related mate- 
rial damage, subsidence-control measures, 
subsidence-monitoring procedures, and 
subsidence law. 



This report describes subsidence tech- 
nology required by mine planners , key- 
words developed for characterization of 
references, rationale used for selecting 
and rating references in appendix A, and 
availability of references. 

Table 1 lists 167 references selected 
for annotation. It identifies the con- 
tent of each reference and rates the con- 
tent of each reference with respect to 
its applicability to the given subject 
areas. The table is cross-referenced, 
subject versus reference, to assist users 
in locating information on a specific 
area of subsidence technology or on a 
specific subsidence reference. 

Appendix A is an annotated bibliography 
of the references in table 1 and provides 
further information on each article. In- 
cluded in each annotation is biblio- 
graphic information and a brief descrip- 
tion of the content, ease of use, and 
applicability of subsidence information. 

Appendix B is the subsidence informa- 
tion center bibliography, including all 
references in appendix A. Of the 767 
references listed in appendix B, approxi- 
mately 600 were assessed for possible in- 
clusion in appendix A. The remaining 
articles were not assessed because they 
were out of print, not available in 
English, or not attainable. 

Since most engineers who apply the sub- 
sidence technology have neither the time 
nor money to expend on an extensive 
search for subsidence literature, it was 
felt that it would be appropriate to 
assess only those articles that are read- 
ily available to U.S. subsidence engi- 
neers and mine planners. However, all 
references were included in appendix B 
for completeness. Of the approximately 
600 references obtained for assessment, 
only 167 articles were annotated. These 
articles were considered by the authors 
to be representative of state-of-the- 
art technology for the given key subject 
areas. The annotation of over 600 arti- 
cles would provide an unwieldly reference 
that would have been costly and time con- 
suming to produce. 



ACKNOWLEDGMENTS 



Larry R. Powell, geologist, Twin Cities 
(MN) Research Center, Merle T. Bernstein, 
librarian, Twin Cities (MN) Research Cen- 
ter, and Betsy Chapel, librarian, Denver 
(CO) Research Center, are acknowledged 
for their efforts in obtaining and pro- 
viding subsidence references assessed in 
this report. 



This project received strong support 
and encouragement from the Office of Sur- 
face Mining and was developed and closely 
coordinated with that organization from 
the outset. 



SUBSIDENCE TECHNOLOGY REQUIRED BY MINE OPERATORS 



To control, mitigate, or prevent 
mining-related subsidence damage, mine 
planners must be able to adequately es- 
timate the location and magnitude of ver- 
tical and horizontal displacement, cur- 
vature, tilt, and strain at the ground 
surface. Although it is impossible to 
totally eliminate surface effects from 
underground mining, adequate subsidence- 
prediction methods used in conjunction 
with proper mine-design and damage- 
mitigation techniques can minimize ad- 
verse surface effects. 



State-of-the-art subsidence technology 
is scattered throughout numerous institu- 
tions and is unknown or unavailable to 
many mine planners. This report attempts 
to minimize this problem by locating, 
assessing, rating, and categorizing this 
information with respect to five key sub- 
jects: (1) prediction methods, (2) ma- 
terial damage, (3) subsidence control, 
(4) subsidence monitoring, and (5) sub- 
sidence law. Information relating to 
these subjects can assist mine operators 
in complying with Public Law 95-87. 



REFERENCE ASSESSMENT, RATING, AND CATEGORIZATION 



The following five key subjects were 
used to assess, rate, and categorize sub- 
sidence literature. They represent the 
areas of subsidence technology that will 
assist mine planners in developing a 
subsidence-control plan in accordance 
with Public Law 95-87. 



• Hydrologic damage to surface wa- 
ter including rivers, streams, and sur- 
face drainage. 

• Hydrologic damage to ground wa- 
ter systems. 

3. Subsidence Control 



1. Prediction Methods 

• Means of predicting vertical 
ground displacements at the surface. 

• Means of predicting horizontal 
ground displacements at the surface. 

• Applicability to the Appalach- 
ian Coal Region. 

• Applicability to the Illinois 
Coal Basin. 

• Applicability to the Rocky Moun- 
tain Coal Region. 

2. Material Damage 

• Damage to surface structures. 

• Damage to subsurface structures. 



• Controlling subsidence with 
properly designed underground-mine 
layouts. 

• Controlling or limiting sub- 
sidence with backfilling techniques. 

• Minimizing structural damage 
through design and construction (sur- 
face measures) . 

4. Subsidence Monitoring 

• Design of monitoring systems for 
measuring surface effects. 

• Instrumentation required for 
monitoring systems. 

• Survey methods for measuring 
vertical and horizontal displacements. 



• Surveying required for subsid- 
ence monitoring. 

• Data processing methods for 
subsidence data and information. 

5. Subsidence Law 

• Federal laws that relate to min- 
ing subsidence. 

• Laws that relate to mines in the 
Appalachian Coal Region. 

• Laws that relate to mines in the 
Illinois Coal Basin. 

• Laws that relate to mines in the 
Rocky Mountain Coal Region. 

• Laws in foreign countries that 
relate to mining subsidence. 

All subsidence references listed in 
appendix B were analyzed to determine 
their applicability to these five key 



subjects. If the reference was germane 
to one or more keywords , an attempt was 
made to obtain the article. If the arti- 
cle was obtained and selected for annota- 
tion, it was assessed and rated with 
respect to each key subject. 

Each reference was rated either S, G, 
or E to indicate its relevancy in the 
specific area (key subject). The rat- 
ing S signifies a satisfactory refer- 
ence that contains general information 
of limited scope. A rating of G indi- 
cates a good reference that contains a 
full breadth of information on the given 
subject but lacks specific information. 
A rating of E indicates an excellent 
reference because it contains specific, 
comprehensive information. The absence 
of a rating indicates that the reference 
does not pertain to that key subject. 



AVAILABILITY OF INFORMATION 



Prior to the Surface Mining Control and 
Reclamation Act of 1977 (Public Law 95- 
87) , there was limited concern in the 
United States about the problem of mine 
subsidence. Thus, subsidence research 
for U.S. mining conditions was limited. 
In contrast, European mining engineers 
were greatly concerned with mine subsid- 
ence because of high population densities 
that increased the probability of damage 
to surface structures. Therefore, most 
state-of-the-art subsidence technology is 
derived from European experience. How- 
ever, it is not known how much, if any, 
of this foreign technology is applicable 
to U.S. conditions, and information that 
does apply might be difficult to obtain. 
Good sources of subsidence information 
in the United States are colleges and 
universities with mining departments, 
and a few State and Federal agencies. 



Federal agencies that might have subsid- 
ence information include mining-research 
and mining-regulatory agencies , such as 
the Bureau of Mines, the U.S. Department 
of Energy, the U.S. Geological Survey, 
and the Office of Surface Mining Reclama- 
tion and Enforcement. State agencies 
that may have access to subsidence infor- 
mation include State mining and geologi- 
cal surveys. In addition, the articles 
annotated in appendix A are available for 
consultation at the Denver (CO) Research 
Center. 

Based on the number of subsidence arti- 
cles published since 1977, the amount of 
subsidence research being performed in 
the United States has increased dramat- 
ically, and there will no doubt be a fur- 
ther concentration of research on this 
subject in the future.

APPENDIX A. —ANNOTATED BIBLIOGRAPHY OF SELECTED REFERENCES 

1. Abel, J. F. Surface Subsidence Monitoring Guidelines. (U.S. Geol. Surv. con- 
tract 14-08-0001-18822, CO School Mines). June 30, 1982, 11 pp. 

Contains suggested guidelines for monitoring subsidence over longwall and 
room-and-pillar retreat mines. Included are details on monument-layout patterns, 
monument construction and installation, monument spacing, survey timing, and strain- 
measurement procedures. A rationale is provided for these guidelines. 

Should be useful for those planning a subsidence-monitoring program. 

2. Abel, J. F. , and D. W. Gentry. A Longwall Subsidence Prediction Model. Pres. 
at Am. Soc. Civil Eng. Natl. Spring and Continuing Education Conv. , Pittsburgh, PA, 
Apr. 24-28, 1978, session 71. ASCE preprint 3293, pp. 56-76. 

Presents a preliminary subsidence-prediction model for the York Canyon coal 
seam. Data for the model were obtained from an instrumentation program implemented 
at the York Canyon Mine, near Raton, NM. The prediction model provides an excellent 
fit to collected data, however, the application of this model to other geologic 
environments is unproven. 

Should be useful in predicting subsidence over coal mines with geology similar 
to that found at the York Canyon Mine. The accuracy of this model, however, has not 
yet been proven. 

3. Adamek, V. , and P. W. Jeran. Evaluation of Existing Predictive Methods for 
Mine Subsidence in the U.S. Chapter 7 in Workshop on Surface Subsidence Due to Un- 
derground Mining, ed. by S. S. Peng and M. Har thill (Morgantown, WV, Nov. 30-Dec. 3, 
1981). WV Univ., Morgantown, WV, Mar. 1982, pp. 88-89. 

Two existing prediction methods are evaluated for use in the United States; 
an influence function (Bals theory), and a profile function (hyperbolic). These 
methods were applied to several field-measured subsidence profiles over U.S. coal 
mines. The results of these comparisons are described in detail. An appendix pro- 
vides information of the application of Bals theory. 

These prediction methods might be found useful in areas where stratigraphic 
conditions are not conducive to bridging. However, no proof of validity for these 
methods in any area of the United States is offered. 

4. . Evaluation of Surface Deformation Characteristics Over Longwall Panels 

in the Northern Appalachian Coalfield. Chapter 17 in State-of-the-Art of Ground Con- 
trol in Longwall Mining and Mining Subsidence (Soc. Min. Eng. AIME Fall Meeting, 
Honolulu, HI, Sept. 4-9, 1982). Soc. Min. Eng. AIME, Littleton, CO, 1982, pp. 183- 
198. 

Details the characteristics of surface deformations, including subsidence, 
inclination, curvature, and horizontal strain. These characteristics, based on data 
obtained by direct field measurements over three longwall panels in the northern 
Appalachian coalfield, are compared with computed values determined by Bals' and 
Knothe's prediction theories. The results of the comparison are discussed and con- 
clusions are drawn as to the effectiveness of the two theories. 

Provides an excellent analysis on the validity of two European surface- 
deformation prediction theories when applied to geological conditions found in the 
Appalachian Coal Region. The material is intended for use by persons familiar with 
subsidence engineering.

Provides information on pumped-slurry backfilling procedures used for control- 
ling subsidence in abandoned room-and-pillar mines that have become flooded or are 
otherwise inaccessible. The article describes a demonstration project performed in 
Scranton, PA, in 1972, and details the use of mine waste as fill material. Recommen- 
dations are made for further hydraulic-backfilling research. 

Good, informative source of background information on backfilling methods for 
abandoned coal workings. However, it does not contain technical information on back- 
filling methods and procedures. 

6. Allgaier, F. K. Subsidence Monitoring Over Western Coal Mines. Chapter 12 in 
Workshop on Surface Subsidence Due to Underground Mining, ed. by S. S. Peng and M. 
Harthill (Morgantown, WV, Nov. 30- Dec. 2, 1981). WV Univ., Morgantown, WV, Mar. 
1982, pp. 156-161. 

Briefly describes the subsidence-monitoring equipment and procedures used at 
five coal mines in Colorado and Utah. Contains information on network layout, monu- 
ment location and installation, monument construction, survey equipment, and data 
processing. Illustrations and drawings are provided. 

Does not provide a comprehensive study of subsidence-monitoring methods and 
techniques. It is, however, easy to read and understand and does provide information 
on basic monitoring procedures. It is a good reference for those who are planning a 
subsidence-monitoring program but are unfamiliar with existing procedures. 

7. . Surface Subsidence Over Longwall Panels in the Western United States. 

Chapter 18 in State-of-the-Art of Ground Control in Longwall Mining and Mining Sub- 
sidence (Soc. Min. Eng. AIME Fall Meeting, Honolulu, HI, Sept. 4-9, 1982). Soc. Min. 
Eng. AIME, Littleton, CO, 1982, pp. 199-209. 

Describes an ongoing research program being conducted in central Utah on sur- 
face subsidence prediction. The geology, mine plan, and survey network is outlined 
for the three study sites involved. A brief discussion of several prediction methods 
is presented, followed by a comparison of measured values from the study sites with 
results of two prediction methods; the NCB (National Coal Board) method, and the 
Donets profile function developed for the Donets coalfield in the Soviet Union. 

Would be helpful to the mine operator interested in subsidence prediction 
methods. Also included is a brief discussion of subsidence monitoring and surveying 
techniques. 

8. . Surface Subsidence Over Longwall Panels in the Western United States: 

Monitoring Program and Preliminary Results at the Deer Creek Mine, Utah. BuMines 
IC 8896, 1982, 24 pp. 

A preliminary report on a case history study being performed over four adja- 
cent longwall panels located in central Utah. Provides a description of the site, 
localized geological data, and preliminary subsidence results. Discusses the design 
of a subsidence-monitoring system including monument location, monument spacing, mon- 
ument construction, installation procedure, survey schedule, and survey procedures. 

Provides the basic information needed for a general understanding of subsid- 
ence monitoring design, procedures, and equipment. Information from the case study 
can be used to estimate labor, time, and economic requirements for similar monitoring 
projects.

at Brynmawr, South Wales. Paper in Proceedings of the Institution of Civil Engi- 
neers, v. 2. pt. 3, No. 3, Dec. 1953, pp. 345-397. 

Describes construction of a factory over abandoned room-and-pillar and long- 
wall coal workings. Contains technical information and the rationale for the ground 
survey, ground treatment, foundation, and structural design work required. The ap- 
pendix provides tables that indicate the mathematics involved in the design theory. 
Numerous photographs, drawings, and diagrams are also included.

Excellent reference for those planning to build structures in areas of possi- 
ble mine subsidence. It relates directly to structures being built over abandoned 
workings , but can be applied to current or future mining areas where the mining meth- 
od and layout are known. Would be most easily understood by someone with a back- 
ground in building design or construction. 

10. Ashmead, D. C. How the Kingston Coal Company Reduces Subsidence and Conserves 
Coal by Rock Filling and Silting. Coal Age, v. 20, Aug. 1921, pp. 167-171. 

Investigates backfilling methods used by the Kingston Coal Co. in Pennsylva- 
nia. Specific sections detail the composition of the silt and fill, the construction 
of the pumping lines, the maintenance of the lines, the backfilling procedures, and 
the overall effectiveness of the system. 

Provides good information on a specific backfilling system for an underground 
mining operation and should be of use to those interested in backfilling techniques. 

11. Australasian Institute of Mining and Metallurgy. Proceedings of the Jubilee 
Symposium on Mine Filling (Mount Isa, Australia, Aug. 19-22, 1973). 1973, 282 pp. 

Details research on fill properties and filling techniques. 

Should be of use to those interested in controlling subsidence by backfilling 
methods.

Including Pneumatic Stowing and Rapidly-Advancing Faces. Min. Eng. (London), v. 
120, Apr. 1961, pp. 552-569. 

Discusses the effects of packing and stowing systems on surface subsidence and 
resulting surface damage in shallow workings. Compares amounts of subsidence record- 
ed for different packing and stowing systems where both a full and partial area of 
influence have been worked. Also compares the surface effects of subsidence from 
rapidly advancing faces versus conventional machine mine workings. Application of 
this research is presented in a case-history study of an undermined viaduct in Eng- 
land. Numerous tables present clearly the data used to outline results and draw con- 
clusions. A discussion of the paper by knowledgable subsidence researchers with the 
authors follows the text. 

Good reference for techniques on limiting the amount of subsidence with the 
use of backfilling methods. A technical background in mining engineering is 
recommended. 

13. Barla, G. B. , and S. Boshkov. Investigations of Differential Strata Movements 
and Water Table Fluctuations During Longwall Operations at the Somerset Mine No. 60 
(Dep. Energy contract ET-76-C-01-9041, Columbia Univ.). 1978, 49 pp.; NTIS 
FE-9041-1. 

Results of research done at the Somerset Mine No. 60 near Washington, PA, in- 
volve the instrumentation and monitoring of water table fluctuations and differential 
strata movements over a longwall coal mine. A description of the instrumentation and 
results of the study are included. Numerous photographs, drawings, and diagrams 
supplement the text. 

Should be useful to those planning to monitor the hydrologic effects of long- 
wall mining. This publication is most easily used by those familiar with geomechani- 
cal logging techniques. 

14. Barr, B. I. G. , and R. Delpak. Prediction of Ground Movement in Areas of Min- 
ing Subsidence. Highway Eng., v. 21, June 1974, pp. 18-22, 36. 

Deals with the estimation of surface strains and deflections caused as a re- 
sult of longwall mining. The Sims-Bridle method of predicting displacements is dis- 
cussed and displacement-calculation procedures are detailed. Sample calculations and 
a computer-program flow chart for the prediction method are also provided.

Could be useful for predicting strain over a longwall panel. However, this 
method was developed for geologic conditions found in England and therefore does not 
necessarily apply directly to U.S. coalfields.

Inst. Min. Eng. (London), v. 114, 1954-55, pp. 223-253. 

Describes precise subsidence surveying techniques used in the Yorkshire Coal- 
field in England. Conclusions based on these measurements are made relating to 
maximum possible subsidence, angle of draw, and the general development of ground 
movement. Discusses the importance of traveling or dynamic ground movements and the 
variations in normal subsidence development that occur when packing is increased or 
partial extraction by strip working is used. Also discusses the question of surface 
damage to structures and the possibility of minimizing such damage by special under- 
ground layout. A successful case of minimizing damage to a large building by a de- 
liberate cancellation of strains is described in detail. 

Good reference on the minimization of subsidence damage through underground 
layout. Although only one example is described, it demonstrates that with proper 
mine design, surface damage can be reduced.

Layer — A Model for Subsidence in Karst Terrains. U.S. Geol. Surv. OFR 79-1094, 1979, 
13 pp.

methods to the subsidence above longwall panels in the United States; the use of the 
"rubble model" to describe the behavior of broken strata as it distends when it falls 
to the mine floor and then is subsequently compacted as it is loaded by overlying 
strata; and the application of physical modeling techniques (centrifuge simulations) 
and numerical techniques to study the failure mechanisms in highly structured stra- 
tigraphy. The capabilities of the modeling and numerical techniques are illustrated 
by comparing their predictions to the results of a field case that has complicated 
stratigraphy.

National Laboratories. 

137. Swain, H. Successful Design for Mining Subsidence. Archit. J., v. 143, May

Describes a building construction system (CLASP) designed for structures 
located over undermined areas. Rather than depending on strength, the buildings are 
designed to depend on lightness and flexibility to withstand the effects of mine sub- 
sidence. There is a brief description of the design of these articulated buildings 
and their key component: the diagonal spring-loaded wind brace. These braces permit 
the buildings to resist wind forces but compress to allow the building frame to ad- 
just to subsidence. CLASP buildings were tested for 14 years; the results of a dam- 
age survey are provided. 

Excellent reference for those planning to build structures on areas that 
might be subjected to subsidence.

Investigates data collected from 16 longwall panels in the northern Appalach- 
ian basin, paying particular attention to the effects of rock lithology, excavation 
width, and panel depth on the subsidence factor. Based on this data, the subsidence 
factor is expressed in terms of the width-to-depth ratio by an exponential equation. 
The parameters of the equation vary with the lithology of the site. 

Discusses a method of subsidence prediction that takes into account the 
lithology of a particular site. The analysis is rather technical, and therefore a 
technical background would be helpful for the understanding of this material.
